2.6.4 USB Communication
The USB port is a USB 2.0 port. It also complies with the USB Test and Measurement Class (USBTMC)
Standard. Communications with this port requires the host computer to have a USBTMC driver available. All
commands and queries through this port must be terminated with a Line Feed character.
The cable required to make this connection is a USB 2.0 A-B peripheral device cable. The cable can be no
longer than 5 meters. If a longer distance is required a USB hub must be used. A cable carrying the official
USB logo is recommended.
When connected to a PC running Windows 2000 or XP a window will pop-up labeled Hardware Wizard. If
this PC has National Instruments LabView installed it will have a USBTMC driver that will work with this port.
This driver will allow the device to be easily controlled using National Instruments Measurement and
Automation Explorer or LabView. It should be noted that the USBTMC driver provided by National
Instruments is a Virtual Instrument Software Architecture (VISA) driver which can be used with other
programming languages besides LabView. For more information on this please consult the National
Instruments Website found at www.ni.com .
NOTE: All firmware updates are done through the USB port.
2.6.5 Ethernet Communication
The Ethernet port allows remote control through a Transmission Control Protocol (TCP) data channel. All
commands and queries through this port must be terminated with a Line Feed character.
By default, this port is setup to work on a network with a Dynamic Host Configuration Protocol (DHCP) server.
Upon connection, an Internet Protocol (IP) address is assigned based on the internal Media Access Control
(MAC) address. The MAC address is printed on a label located near the Ethernet port.
If the connected network does not have DHCP enabled, then the device can be assigned an IP address by the
user. To do this, download the utility called DeviceInstaller
TM
from www.Lantronix.com . For assistance using
this utility please consult the utilities embedded help file.
The DeviceInstaller
TM
utility will scan the network and find all connected Lantronix Ethernet devices. This list
of found devices will include any connected AR Ethernet devices. By selecting one of the connected devices
from the list, its IP address and subnet mask can be changed along with a number of other settings. One should
use caution in adjusting any settings he/she is unfamiliar with as doing so may cause the port to become
unresponsive. By default the port for the TCP data channel is 10001.
* DHCP is a protocol used to assign a dynamic IP address to a device. Network server software will assign
an available IP address to a device when it is connected and powered on. Different IP addresses may be
assigned at different times.
